Filter by:Fluoropyrimidine chemotherapy agents , such as 5-fluorouracil and capecitabine, are occasionally associated with cardiac toxicity. Clinical fluoropyrimidine cardiotoxicity is infrequent, but subclinical toxicity may be much more common. Cardiac toxicity may be less frequent with S-1 as compared with 5-fluorouracil and capecitabine, but head-to-head comparisons are lacking. The purpose of the study is to compare 2 measures of subclinical coronary artery microvascular dysfunction, the coronary flow reserve and the coronary flow response to a cold pressor test, in a patient population who are being treated for adenocarcinoma of the gastrointestinal tract with one of 2 oxaliplatin-containing regimens, either with oxaliplatin plus S-1 or with oxaliplatin plus capecitabine.
The overall objective of this pilot study is to determine whether multispectral imaging increases the diagnostic accuracy of the current standard of high-definition white-light endoscopy for the detection of gastric neoplasia (high grade dysplasia or cancer). As part of an NCI-funded RO1, the investigators goal is to develop a multispectral endoscopic platform that can be used to survey a large surface area and, potentially, serve as a "red flag" for microendoscopic imaging of small areas. In prior ex vivo evaluations of surgical and endoscopic specimens, the investigators have identified the optical settings and illumination wavelengths that are complementary to white-light imaging and enhance superficial mucosal and vascular changes associated with neoplasia. Based on this initial testing, vital-dye enhanced fluorescence imaging (VFI) and imaging with High Resolution Microendoscope (HRME) have been identified as modalities that may be complementary to white-light imaging. The goal of this pilot study is to preliminarily determine the accuracy of these modalities during the endoscopic surveillance and detection of gastric neoplasia.
After curative resection, patients with stage IIIB-IV (M0) gastric cancer were given chemotherapy as follows: S-1 orally at 80 mg/m2 divided in two daily doses for 14 days and oxaliplatin at 130 mg/m2 intravenously over 2 h every 21 days as one cycle. S1 was administered for 16 cycles (12 months) and oxaliplatin for 8 cycles (6 months).
The aim of this study is the effect of proton pump inhibitor (PPI) with respect to gastric cancer bleeding in inoperable patients.
This is a Phase 3, multicenter, randomized, double-blind, placebo controlled study of Rilotumumab (AMG 102) with Cisplatin and Capecitabine (CX) for untreated advanced mesenchymal epithelial transition factor (MET)-positive gastric or gastroesophageal junction adenocarcinoma (GEJ).
The purpose of this study is the validation of MMS test to detect active tumor growth in different cancer types before and after therapy, as well as in the course of therapy and for subsequent relapse control compared to standard methods (clinical examination, imaging, tumor markers). It should be consider whether the MMS test has comparable diagnostic accuracy, and thus can replace more expensive or invasive procedures in future.
The investigators hypothesize that the new imaging method Gallium-68-DOTATATE has a higher diagnostic value in the detection of neuroendocrine tumors than the established imaging method Indium-111-Octreoscan. Therefore, the investigators will perform both imaging procedures in patients with suspected or confirmed neuroendocrine tumors. Subsequently, the investigators will compare the diagnostic performance of both methods.
This is a randomized, parallel group, non-blinded phase III trial. Patients with advanced (locoregional or metastatic) gastric cancer not previously treated with chemotherapy for this stage will be randomized in a 1:1 ratio to receive low-TOX (arm A) or EOX (arm B). Randomization will be stratified by performance status (ECOG 0, 1 and 2).
This is a multi-centre Phase 2 study. The study will evaluate the activity and safety of AMG 337 in patients who have MET amplified gastric, gastroesophageal junction or esophageal adenocarcinoma or other MET amplified solid tumors. The study is designed to estimate the objective response rate of AMG 337 by tumor type.
This study will evaluate the efficacy and safety of Herceptin in patients with metastatic or advanced gastric cancer with disease progression during platinum-based or 5-fluoropyrimidine-based chemotherapy. The anticipated time on study treatment is until disease progression.
